| Outcome metric | Prepathway implementation: Jan. 2018 to May 2018 (n=392) | Postpathway implementation: Aug. 2018 to Sept. 2019 (n=1079) | OR (95% CI) | P value | Completed match ATTa | Completed match P valuea |

Data are presented as mean±SD or number (percentage), unless otherwise indicated. Some columns may not add to 100% because of missing data.
ATT, average treatment effect on the treated; CD, cesarean delivery; CI, confidence interval; IOL, induction of labor; NICU, neonatal intensive care unit; OR, odds ratio; PPH, postpartum hemorrhage; SD, standard deviation.
